Why does antibiotic resistance matter?

So why does resistance matter when treating patients with Gram-negative bacteria?

Gram-negative bacteria are becoming increasingly resistant to the antibiotics more commonly used for treating infections due to these pathogens. This means we are in danger of losing the ability to treat common infections.

In 2014 a review of global antimicrobial resistance, lead by Jim O’Neil, was begun. The report published in May, 2016 states:

On 27 February 2017 the WHO published a list of bacteria (Global Priority List of Antibiotic-resistant Bacteria To Guide Research, Discovery, and Development of New Antibiotics) for which new antibiotics are urgently needed and the list highlights:

“in particular the threat of Gram-negative bacteria that are resistant to multiple antibiotics. These bacteria have built-in abilities to find new ways to resist treatment and can pass along genetic material that allows other bacteria to become drug-resistant as well…..”
